‘24 hour’ operation
The Grant SpiraVac system will then always automatically operate and fill the hopper every 24 hours
starting from the time it is first switched on using the ‘VACUUM SYSTEM’ ON/OFF switch on the SpiraVac
control panel. This is the automatic ’24-hour’ operating mode of the SpiraVac system.
It is possible to re-set the time that this ’24 hour’ operation occurs to a more suitable time (e.g. during the
evening) to avoid the automatic operation of the vacuum system during the night time.
To do this, simply switch the ‘VACUUM SYSTEM’ switch to OFF wait for about 2 seconds and then
switch back to ON at the time you wish the ’24-hour’ operation to occur. This time will be automatically
stored in the control system memory and the store will then fill at the same time every day (if required).
NOTE
If the power supply to the Spira Boiler and SpiraVac system is interrupted, either deliberately or otherwise
(e.g. a power cut), the built-in timer function will stop for the duration of the power interruption.
Whilst the SpiraVac system will automatically continue to operate in the ’24 hour’ mode when the power is
reconnected, and the original time setting will be remembered, the actual time it will operate to fill the
hopper will now be incorrect, i.e. delayed by the duration of the power interruption.
Example: If the ‘24hour’ mode was originally set to operate at 6.00pm every day, but a power cut lasting
1 hour occurred, the ‘24hour’ will now operate at 7.00pm after the power is reconnected.
It will therefore be necessary to reset the ‘24 hour’ mode following a power interruption if the original ’24
hour’ mode operating time setting is still required. To do this, simply switch the ‘VACUUM SYSTEM’
switch to OFF, wait for about 2 seconds and then switch back to ON at the time you wish the ’24-hour’
operation to occur.
Priming the Auger
The pellet hopper auger can now be primed. Follow the procedure given in Section 10.7 of the Installation
& Servicing Instructions provided with the boiler.
After the pellet hopper auger is fully primed, leave the ‘VACUUM SYSTEM’ switch set to ON.
